In april we went to VIetnam, my wife, grandchild 7 and I, first trip to Vietnam, but not the last.
Since we live in Sisaket province we took the bus from Ubon R to Pakse in Laos and stayed there for a couple of days. Then we took the bus from Pakse to Hue and stayed in Hue 3 days. The bus ride was challenging on the Lao side but we survived. Hue was OK with sightseeing and restaurants, we are not into shopping, so can't tell about that.
Then with the train from Hue to Da Nang because grandchild and wife had never tried the train, we had a sleeper cabin for ourselves and that was fine.
In Da Nang we stayed for 10 days sightseeing, visiting friends and got visit from family from my homeland, but no shopping. Da Nang was fine for walking around, going to the beach and many restaurants.
One day we vent to Hoi An and that was a disappointment filled up with tourist.
Hotels in both Hue and Da Nang were cheaper than in Thailand for the same standard.
We used Grab for going around in Hue and Da Nang and for the trip to Hoi An, I have never used Grab before and were surprised over how cheap it was.
We left Vietnam for Bangkok and continued our holiday there.
